FOREWORD

The development of organ and tissue transplantation in this country continues to make progress although at a pace many wish could be faster. Many factors continue to challenge the development of organ transplantation. The high cost of doing organ transplantation has been cited as a frequent impediment to doing more transplantation. Yet there has never been a case where organ transplantation in this country has been deferred or put off because the patient cannot afford it. We are fortunate in that the government has been supportive and subsidized heavily the cost of doing transplantation. Almost all solid organ transplantation is done in public hospitals either in the Ministry of Health or Ministry of Higher Education. There have been numerous campaigns in both the print and electronic media to create greater public awareness and although there is a surge of interest after each dramatic report of a donation by a cadaver donor, we are not seeing that many more donation as expected. The organ procurement team will no doubt continue with its efforts to promote cadaveric organ donation. Another factor that has been addressed recently is the organizational and support structure to facilitate transplantation. The Ministry of Health has now reorganized the structure of the transplantation service, developed a national policy on organ and tissue transplantation and allocated substantial funds for human resource development and improvement of facilities. These measures hopefully will bear fruit in the near future.

In recent years much attention were directed to the unsavory aspect of kidney transplantation – the commercial cadaveric transplantation in China and the live donor kidney transplantation in Pakistan and Philippines in particular. Authorities in these countries have now banned such transplantation. The number of kidney transplantations done in China has dropped dramatically and the overall figures for kidney transplantation reported to the National Transplant Registry (NTR) in 2007 was the lowest in many years. Many countries in the world have resorted to increasing the live related donor pool to overcome the shortage of kidneys. In some the number of live related kidney transplantation has overtaken that of cadaveric kidney transplantation. It is time that this country redirects its efforts to improve the live related kidney transplantation program. Many end stage renal failure (ESRF) patients have not been properly counseled on the benefits of transplantation but are often shunted straight to dialysis.

This report continues to document the progress made in organ and tissue transplantation in the country. We are grateful to the centres, the doctors and their staff who have painstakingly collected data and submitted them to NTR. We hoped the data in this registry will be of use to them and can assist them in planning future development, audit activities and stimulate research.

ABOUT THE NATIONAL TRANSPLANT REGISTRY

The National Transplant Registry (NTR) is a Ministry of Health (MOH) supported registry whose aim is to collect information about organ and tissue transplantations in Malaysia. The information allows us to estimate the magnitude of transplant activity in the country. Such information besides being useful to transplantation practitioners, can be used in assisting the MOH, non-governmental organisations, private providers and industry in program planning and evaluation of transplantation services.

The objectives of NTR are to:

1. Determine the frequency and distribution of all types of transplantation activity in Malaysia.

2. Determine the outcomes of transplantation.

3. Determine the factors influencing outcomes of transplantation. 4. Evaluate transplantation services in the country.

5. Stimulate and facilitate research on transplantation and its management. The NTR receives data on organ / tissue transplantation from 3 main sources:

1. The individual doctors who provide transplantation services, who voluntarily report data to the NTR. Data collection will be from seven main types of transplantation services:

• Blood and Marrow Transplant • Cornea Transplant

• Heart and Lung Transplant • Liver Transplant

• Renal Transplant • Heart Valve Transplant • Bone and Tissue Transplant

2. The National Vital Registration system (Jabatan Pendaftaran Negara). Their data is useful for determining or verifying mortality outcomes of transplant patients.

3. Information Documentation Unit of the MOH, which operates the Health Management Information System (HMIS).

NTR SPONSORS

• Medical Development Division, MOH • National Transplant Coordinating Committee • Malaysian Society Of Transplantation

REPORT SUMMARY

1. BLOOD AND MARROW TRANSPLANTATION

There were a total of 1174 haematopoietic stem cell transplantations reported to the Registry between 1987 and 2006; 797 were functioning by the end of 2006.

The majority of all transplants (72%) were for malignant disorders and most of these are haematological malignancies like leukaemia and lymphoma. The main non-malignant disorders transplanted were thalassaemia and aplastic anaemia.

There were 124 new transplantations done in Malaysia in 2006 with 11 follow-up centres for transplant recipients.

Mean age of new transplant patients in 2006 was 24 + 19 years; 59% were male, 44% Malay, 38% Chinese, 7% Indian and 11% others. Autologous transplants accounted for 33%. Seventy-eight percent of the transplant source was from peripheral blood stem cells and 93% were from Human Leukocyte Antigen (HLA) identical donors.

In 2006, 25 of prevalent transplant recipients died. Underlying disease and infection were the commonest causes of death accounting for 44% and 32% respectively.

2. CORNEA TRANSPLANTATION

There were 46 centres which provided cornea transplantation data.

One hundred and seventy-four new cornea transplantations were reported in Malaysia in 2006. Mean age of new transplant recipients in 2006 was 44 + 22 years. Of these, 67% were male. Thirty-five percent of recipients were Malay, 33% were Chinese, 23% were Indian and 9% were other races.

The primary diagnoses for cornea transplantation recipients in 2006 were keratoconus (19%), pseudophakic bullous keratopathy (17%), cornea perforation (15%), cornea scars (10%), microbial keratitis (6%), other (non-pseudophakic) bullous keratopathy (6%), and failed previous cornea grafts (5%).

Sixty percent of recipients were legally blind before their transplant surgery.

In 2006, 55% of donated corneas were from the USA, 24% from Sri Lanka and 20% from local sources. The mean age of the donors was 55 + 16 years.

(16)

There were a total of 17 heart transplantations reported to the Registry between 1997 and 2006; seven grafts were functioning at the end of 2006 and all were followed up in Institut Jantung Negara.

There was only 1 heart transplantation done in 2006.

Two thirds of the heart transplant recipients were males and 58% were Indians. The mean age of recipients was 36 + 16 years. Ischaemic cardiomyopathy was the commonest primary diagnosis (9/17) followed by dilated cardiomyopathy (6/17).

Six recipients died in hospital following heart transplantation; four patients succumbed to late deaths after their heart transplant.

The transplant patient survival rate was 59% and 40% at 1 year and 3 years respectively.

Two lung transplantations were performed, one in 2005 and one in 2006. Both of the patients were Indian males and both of them had Idiopathic Pulmonary Fibrosis. Single lung transplantation was performed for the 1st patient and patient remained alive with good quality of life. Double Lung transplantation was performed in the second case in 2006. Unfortunately, this patient succumbed 8 weeks after transplantation due to Cytomegalovirus infection.

4. LIVER TRANSPLANTATION

There were a total of 88 liver transplantations reported to the Registry between 1993 and 2006; 50 grafts were functioning by the end of 2006.

There were 8 new liver transplantations done in Malaysia in 2006. There were 5 follow-up centres for liver transplant recipients in 2006.

Mean age of all transplant patients was 7 + 14 years (range 3 months to 74 years); 57% were male, 50% Chinese, 72% were for biliary atresia. Majority were living donor liver transplantations (80.7%).

At the time of transplantation the main immunosuppressive drugs used were tacrolimus (77%) and steroids (59%).

(17)

5. RENAL TRANSPLANTATION

There were 51 follow-up centres for renal transplant recipients in 2006. Incident rates for renal transplantation were static, from 6 per million population in 1997 to 5 per million in 2006. There were 132 new renal transplants in 2006.

The number of functioning renal transplants has increased steadily from 1083 in 1997 to 1728. The transplant prevalence rate was 65 per million population in 2006.

In 2006, the mean age for new transplant recipients was 37+15 years, 68% were male and 20% had diabetes at the time of transplantation.

Ninety-seven percent of prevalent renal transplant recipients were on prednisolone, 75% on cyclosporine, 17% on tacrolimus, 48% mycophenolate mofetil and 34% on azathioprine.

In 2006, 49 (3%) of prevalent transplant recipients died and 35 (2%) lost their grafts. Infection and cardiovascular disease were the commonest causes of death accounting for 41% and 19% respectively. Death at home was the third commonest cause at 13%. Renal allograft rejection accounted for 71% of graft loss.

The overall transplant patient survival rate from 1993 to 2006 was 95%, 91%, 88% and 80% at 1 year, 3 years, 5 years and 10 years respectively, while the overall graft survival rate for these years was 92%, 85%, 79% and 63% respectively.

6. HEART VALVE TRANSPLANTATION

There were a total of 167 heart valve homografts reported to the Registry between 1996 and 2006; 148 grafts were functioning at the end of 2006. Eighty-three were aortic and 84 were pulmonary valves.

Mean age of all heart valve transplant patients was 11 + 10 years (range 3 months to 70 years); 51% were male, 61% Malay.

1.0 INTRODUCTION

This is the third report on Blood and Marrow Transplant activities in Malaysia up to December 2006 as recorded by the Blood and Marrow Transplant Registry under the umbrella of the National Transplant Registry.

The registry continues to be vital as it would serve the following purpose:

1. Provide an accurate record of the number of haematopoietic stem cell transplantations performed in the country.

2. Reflect the changing trends in patient numbers, indications for transplant, mode of transplants and centres involved.

3. Report on the outcome of haematopoietic stem cell transplantation which would enable national and international comparisons.

4. Provide data which could guide future needs and directions in the field of haematopoietic stem cell transplantation.

Third Report of the

1.1 STOCK AND FLOW

At the time of the third report, a cumulative total of 1174 transplants had been conducted by transplant centres in the country. The number of transplants recorded in 2006 was 124, which was a slight decrease from the previous year’s total of 147. In 2006, Ampang Puteri Specialist Hospital began transplantation services to add to the number of transplant centres. Meanwhile Hospital Kuala Lumpur (adult transplants) moved to a new premise in Hospital Ampang.

Third Report of the

1.2 RECIPIENTS’ CHARACTERISTICS

Recipients were predominantly male (59% males, 41% females) (Table 1.2.1). The largest ethnic group of transplant recipients was Malay (44%) followed by Chinese and Indians (Table 1.2.2). The young median age reflected the paediatric bias in the registry as transplants first started in paediatric patients while the adult centres started later in 1993 (Table 1.2.3). However over the past 10 years there has been a gradual increase in the median age of recipients and patients older than 60 years of age have had access to transplantation.

The majority of transplants (about two-thirds) were for malignant disorders and most of these were haematological malignancies like leukaemia and lymphoma (Table 1.2.4). The number of patients transplanted for chronic leukaemia (mostly chronic myeloid leukaemia) showed a steady decline over the past few years. This probably reflected the preferential usage of imatinib mesylate as first line management of chronic myeloid leukaemia. The bulk of non-malignant disorders requiring transplants were thalassaemia and aplastic anaemia.

1.3TRANSPLANT PRACTICES

The majority of transplants (67%) done remained allogeneic with 83 patients transplanted compared with 41 patients who underwent autologous transplants. Donors for allogeneic transplants were HLA matched in 93% of cases while 1 and 2 antigen mismatches made up the remaining 7%. No patient received a graft with > 2 antigen mismatches. Although most donors were siblings, the number of unrelated donors had increased and contributed to 13% of all allogeneic transplants performed in 2006. There was a predilection to use of peripheral blood stem cells compared with bone marrow or cord blood and this was reflected in the 78% of transplants using this stem cell source. Not unlike global trends, the number of cord blood transplantations also showed a slight increase.

1.4TRANSPLANT OUTCOMES

The major cause of death continued to be relapse/underlying disease (44%) with sepsis (32%) being the second commonest cause of death. Surprisingly veno-occlusive disease of the liver contributed 12% of deaths while graft-versus-host disease became the fourth most common cause of death (8%) (Table 1.4.1). Overall Kaplan Meier survival analysis showed a trend in favour of younger patients (Fig 1.4.3).

1.5DISEASE-FREE SURVIVAL

This section shows the breakdown of disease-free survival by disease category. For malignant disorders like Acute Myeloid Leukaemia and Non-Hodgkin’s Lymphoma, where there were allogeneic or autologous donors, the outcome with allogeneic transplants was superior to autologous transplants.The remaining malignant disorders were all treated with allogeneic transplants.

Generally outcome for paediatric patients was superior to adult patients for most diseases except for Acute Lymphoblastic Leukaemia and Aplastic Anaemia.

2.0 INTRODUCTION

Cornea transplantation surgery allows restoration of vision in patients with corneal blindness. Cornea transplantation in Malaysia dates back to the 1970’s. Today it is widely performed by ophthalmologists throughout the country both in the government and private sectors with each centre maintaining its own data.

The National Transplant Registry (NTR) was established in December 2003. The cornea transplant section of the NTR was given the task of establishing a systematic centralised data collection centre for all cornea transplantation performed in the country.

A total of 46 centres registered and agreed to provide information on retrospective and prospective cornea transplant activities. A total of 46 contributing surgeons participated in the NTR – Cornea Transplant section. Participation was voluntary.

Retrospectivedata (from 1998 to 2003) on cornea transplant activities were collected to identify the trend of cornea transplant surgery in the past few years. Retrospective data collected was recorded on the Retrospective Cornea Transplant Notification Form (Form R-mds). This was limited to minimal data set which were i) demographic data, ii) type of cornea transplant surgery and iii) primary diagnosis for cornea transplantation. All surgeons agreed to provide all information required in the Retrospective Cornea Transplant Notification Form.

(56)

The Cornea section of the NTR will be discussed under 3 sections.

Section 2.1 and Section 2.2 covers notification data on cornea transplantation over 9 years from 1998 to 2005. Effort was made to ensure that all cases of cornea transplantation were reported. To the best of our knowledge, this report provides information on all cornea transplants performed in the country.

Section 2.3 covers prospective notification data on cornea transplantation (from 2004 onwards) from surgeons who sent a complete data set.

2.1 CORNEA TRANSPLANT ACTIVITIES AND TRENDS (1998-2006)

The number of cornea transplants performed showed an increasing trend from 119 in 1998 to 221 in 2001, following which there was a slight decline in 2003 followed by a progressive increase each year to 192 in 2005 but this declined to 174 in 2006 (Table 2.1.1).

Penetrating keratoplasty was the most frequent type of cornea transplant surgery and was performed in 93% of cases (Table 2.1.2).

2.3.2 Pre-transplant Data

Regrafts were performed in 10% of cases (Table 2.3.2.1). Corneal vascularisation was the most frequently encountered pre-operative ocular co-morbidity, followed by ocular inflammation and glaucoma (raised intraocular pressure).

Sixty-eight percent of cases were legally blind (vision 3/60 or worse) prior to cornea transplantation (Table 2.3.2.3).

2.3.3 Donor Details

Eye Banks in the United States of America (USA) were the most frequent source of the corneal tissues (Table 2.3.3.1). The majority of donors were elderly patients with a median age of 58 years (Table 2.3.3.2). Optisol GS was the commonest cornea tissue storage medium used at 76% (Table 2.3.3.3). The major causes of death of the donors were related to the cardiac or circulatory system (30%) followed by malignancy (15%) (Table 2.3.3.4).

2.3.4 Transplant Practices

Penetrating Keratoplasty (PK) was the commonest type of surgery performed (88%) (Table 2.3.4.1). Cornea transplantation was performed in combination with other surgical procedures in 20% of cases. Cataract extraction, with or without intraocular lens implantation (IOL), was the commonest combined procedure (Table 2.3.4.2). The recipient graft size ranged from 2mm to 10mm, with the median recipient cornea graft size being 7.5mm (Table 2.3.4.3). The majority of cases had the donor tissue over-sized by 0.5mm (Table 2.3.4.4). The commonest suture technique was interrupted sutures (Table 2.3.4.5).
